Excalibur's XML Utilities provide simplified wrappers for XML parsers, transformers and XPath evaluators.
It also provides interfaces and classes useful for constructing a pipeline of XML components by defining
interfaces for consuming and producing XML in either SAX or DOM formats.

A very common problem is resolving a source, which means finding a source using a URI. The source resolver of
Avalon Excalibur is a component helping you in this task. It resolves sources from a given URI. The URI can use
all available protocols of the JRE. In addition own protocols can be plugged-in. So using the standard protocols
like HTTP, FTP or file can be handled in the same way, like dealing with custom, self-build protocols such as
myxmldatabase://root/documents/test.xml.
